A photoluminescent, light-emitting golf ball comprises a substantially solid core with an outer shell, both formed of a light transmissive material. Photoluminescent particles are distributed within the light transmissive material. A light-emitting circuit assembly embedded within the core includes at least one battery, a control circuit coupled to the at least one battery, a plurality of light-emitting diodes coupled to the control circuit, and an impact switch electrically connected between the battery and the control circuit. The control circuit actuates the light-emitting diodes for a predetermined time period in response to an impact of the golf ball by a golf club. Actuation of the light-emitting diodes by an impact on the golf ball excites the photoluminescent particles, causing the particles to glow in excess of the predetermined time period of actuation of the light-emitting diodes.

Abstract:

This invention relates to a means for more efficiently and more safely providing self-luminous lighting devices for use in signs, markers, indicators and the like. The present invention provides self luminosity by means of a plurality of glass or polymer microspheres containing both a light-emitting phosphor and a radioactive gas. The “soft” emission of electrons from the beta emitting gas cannot penetrate the glass or polymer wall of the microspheres, thereby constituting no radiation hazard. A further advantage of the present invention is that the plurality of individual containment microspheres minimizes the escape of radioactive gas in the event of any physical damage to an assembly of such microspheres. A still further advantage of the invention is that the radioactive gas completely surrounds the phosphor particles, thus causing light emission from one hundred percent of the surface of the particles.
